It's also helpful for getting rid of damaged and unwanted frames and thinning out GIFs. This mode allows you to quickly discard the beginning or end of a GIF, cut out the middle part of an animation, or remove just a couple of static frames from a GIF.

In this case, frames five to ten (inclusive) and frames twenty-four and thirty-nine will get cut. You can combine a frame range with individual frames and enter something like "5-10, 24, 39". This option also accepts a range – for example, "10-40" will cut a range of frames from a GIF.

For example, if you enter "2, 7, 45", then frames two, seven, and forty-five will get discarded. Here, you can enter specific frames that you want to get rid of. The second mode is called "Delete These Frames" and it's paired with the option "Frames to Delete". With this mode, you can optimize your GIF animation as it reduces GIF's size. Similarly, you can remove every third, fourth, or n-th frame from a GIF. In this case, the following frames get deleted: 2, 4, 6, 8, …. You can also delete all even frames if you set the distance to 2 and the starting frame also to 2. In this case, the following frames get deleted: 1, 3, 5, 7, …. For example, you can delete all odd frames if you set the distance to 2 and the starting frame to 1.

This mode periodically removes equidistant frames. The first is called "Delete Every n-th Frame", which lets you delete every n-th frame starting from a particular frame. This is a browser-based program that removes frames from animated GIF files.
